Ion densities and velocities in the inner plasma torus of Saturn

► We make an investigation of the inner plasma disk of Saturn with regard to ion density and ion drift speed using Cassini data. ► A large range of ion densities are found in the plasma disk with a broad maximum in between the orbits of Enceladus and Tethys. ► The average ion drift velocities reaches down to ∼68% of corotation speed at around 5RS.
